AN921 TSM101在温控器的使用
APPLICATION NOTE
TSM101 USED IN A THERMOSTAT
by R. LIOU




This technical note shows how to use the TSM101 Figure 1 : TSM101 Schematic Diagram
integrated circuit to realize a simple Thermostat
controlling a fan in cooling applications.
An example of realization is given with the corre-
sponding calculations.

TSM101 PRESENTATION

The TSM101 integrated circuit incorporates a high
stability series band gap voltage reference (1.24V
2% precision or 1% with the A version), two ORed
operational amplifiers and a current source
(1.4mA) as shown on Figure 1.
